To all whom "it may concern 7 Be it known. that I, CLanKnPuPoND, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in NindowOperating lllechanism, of'whi ch the following is a specification.

One object of my invention is to provide simple, substantial, and easily operated mechanism for swinging on their hinges or pivots, the sashes of one or more lines of windows, regardless of the length of the line or of the number of such sashes or lines.

Another object is to provide a novel form of mechanism for transmitting power from an operating cable or chain to the cables, chains, or rods attached to the sash levers; it being desired that such transmitting mechanism shall be capable of moving two operating rods or cables in opposite directions, and where three such rods'or cables are used, of moving two of them in one direction and one in an opposite direction.

I further desire to provide novel means for connecting the operating rods with hinged or pivoted sashes regardless of whether such pivots orhinges are horizontal or vertical.

These objects and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings, in which :the figure is, a perspective view illustrating my invention as employed in operating a horizontal line of sashes so mounted as to swing on vertical pivots.

When it is desired to operate a line of sashes in which the sashes swing on vertical pivots, I provide two operating rods 5 and 5 both movable in the same direction, and connect to them a third operating rod 6. In this instance each sash has rigidly connected to it two projecting arms 30 each preferably braced by a second arm 31, and connected to the operating rod 5 or 5 as the case may be. by a suitable coupling 32.

In order to transmit power from the operating chain 33 to the operating rods, I

mount four sprocket wheels, of which two,

are shown at 26 on the spindle 22 and provide each of them with a sprocket chain 27. The lower ends of all of these sprocket chains are connected by a cross bar 34, which in turn is coupled to the lower operating rod 6, while the upper'ends of two offthe chains are connected through a cross bar 28 to the operating rod 5. The upper ends. of the Specification of Letters Patent. Patentedjiug, 2a, 1915,

i Application filed July 31, 1909. Serial No. 510,672.

second pairof chains are connected through a secondcross bar 28 to one end of a chain 35 which passes over a suitable pulley 36 and is connected to one end of the operating rod 5. Said pulley 36 is pivotally connected to a wall bracket 37. With this arrangement of parts, the operation of the chain wheel 24 turns the spindle 22 through the worm and worm wheel as before explained, so as to pull the lower operating rod 6, for

example, toward the transmission gear- This results in the two operating rods 5 and 5 being pulled away from said transmission mechanism, so that all of the sashes of the lines are caused to swing on their pivots to an open position ;-it' being obvious that a reversal of this movement will cause closing of said sashes. In some installations one arm is all that is necessary and but one sprocket wheel and chain are required.

The two rods 5 and 5 are supported by the sash arms to which they are connected, while for the support of the rods 6, I provide any suitable number of hangers e9 rigidly connected to the rod 5 and provided with apulley 38 on which said rod 6 rests.

I claim 1. The combination of a plurality of I sashes to be moved; a plurality of parallel longitudinally extending operating members; means for connecting said members to the sashes; means for moving said members longitudinally, the same consisting of a supporting structure having a spindle; a worm wheel and a plurality of sprocket wheels on said spindle; sprocket chains on said wheels all having one end connected to one of said members and having their opposite ends connected to others of said memhers respectively; a worm meshing with said sashes; means for operating said sashes consisting of three parallel members extending adjacent said sashes; means for connecting two of said members to each of said sashes;

and means for longitudinally moving, said direction.

4. The combination of a plurality of sashesysash operating means consisting of three parallel members extending adjacent the sashes; means for connecting two of said members to each ofsaid sashes; with means for longitudinally moving said two latter members in one direction while mov ing the third member in an opposite direc- Copies of this patent'gnay be obtained for five cents each, by addressing the Commissioner of Patents,

tion; the'same consisting of a plurality of sprocket chains connecting one of said mem- 5 bers with both of the others; sprocket wheels for said chains; and Worm gearing for actuatmg sald sprocket wheels.
